RAILROAD SNOW-PLOW AND CAR COMBINED.

SPECIFICATION forming part of Letters Patent No. 376,698; dated-Tanuary17, 1888.

' L Application filed October 30, 1886. Serial No. 217,628. (No model.)

To aZZ whom it may concern:

Be it known that I, JosEPH WooLLEY, a citizen of the United States,residing at Rutland, in the county of Rutland and State of Vermont, haveinvented a new and useful Snow- Plow and Car Combined for Removing Snowfrom Railroads, of which the following is a specification.

My invention relates to an improvement in that class of railroadsnow-plows in which are combined rearwardly and upwardly inclinedsurfaces of a different degree of inclination, mold-boards, and cuttersupon said surfaces.

The objectof my invention is to provide a snow-plow which shall requireless power to successfully operate the same, and which shall at the sametime do its work more effectually than the devices of this classheretofore in use; and with these ends in view my invention 0011- sistsin the'combination,with a forward wedgeshaped inclination, inclinedsurfaces continuing upwardly and rearwardly from the-forward inclineat aless degree of inclination than the same, and downwardly-extendingsides, of the mold-boards provided with a beveled point or cuttingedgeand extending from the center of the upper port-ion of the forwardincline to the rear corners of the plow with agradual increasinglateralcurvature, the outline ofsaid mold-boards from their point to their rearends being vertically concave in cross-section, cutters upon theoppositeedges of the first incline and extending-rearwardly to and upon the rearinclines, the side faces of said cutters tapering upwardly-from theirlower portions and their front edges sloping upwardly and rearwardly andbeing beveled to form a sharp cuttingedge, and a top covering the upperportions of said mold-boards and projecting beyond the edges of thesame.

In the accompanying drawings, Figure 1 is a side elevation of mycomplete device; Fig. 2, a top plan view of the same; Fig. 3, an'endelevation, and Fig. 4 a front elevation.

In the drawings, the reference-letter E indicates the sidesof'a carcarrying and forming a part of my improved snow-plow. The forwardportion of the plow consists of a wedgeshaped nose or projection, D,provided with an upwardly andrearwardly sloping upper surface,WlllChl'EflOllGS its highest point at the line a a, which line alsomarksthe lowest point of surfaces P P, sloping upwardly and rearwardlyto the end of the car, but at a less de gree of inclination than theslope of the first inclination, D. Y Vertical mold-boards B B arelocated upon said inclines P P and D, the beveled point a ofsaidmold-boards being centrally. located upon the upper part of the firstincline, D,

from which point the mold-boards extend to the rear end corners of thecar with a gradual increasing lateral curvature, and the verticalout-line of said mold-boards in cross-section is vertically concave fromthe point it to the rear end of the mold-boards, as shown in Figs. 3 I

and 4; but I wish it understood that the moldboards do not change theirvertical position and form a spiral curve, as has heretofore been thecase.

Beveled cutters G O are located upon the,

opposite edges of the first incline, D, and extend rearwardly asho'rtdistance upon the upper inclines, P P. The side faces of these cutters OG gradually taper upward to their top edges, and their cutting or frontedges, 0', slope, upwardly and rearwardly and are beveled to form asharp cuttingedge, 0'.

being removed in its passage up the inclines, and by constructing thecutters in the above- The cutters limit the width of the cut and guidethe snow 7 described form they offer the least resistance 1 possible tothe passage of the snow.

A horizontal top or roof, A, is secured upon the upper edges of saidmold-boards, and the outer edges of the top are madeto conform to thelateral curvature of the mold-boards and project a short distance'beyondthe edges of the same. p

By constructing the mold-boards, inclines, and cutters in the mannerbefore described, a snow-plow is produced which, when performing itswork, imparts to the snow being removed a gradual upward and lateralmotion in such a mannerthat the resistance offered to the passage of thesnow and the forward movement of the plow is reduced to a minimum.

Having fully described my invention, what I claim as new, anddesire tosecure by Letters Patent, isv 1. In asnow-plow, the combination ofaforward wedgeshaped incline, inclined surfaces wardly from the forwardincline at a less degree of inclination than the same, and thedownwardly extending sides, of the moldboards provided with a beveledpoint or cutting-edge and extending from the center of the upper portionof the forward incline to the rear corners of the plow with a gradual.increasing lateral curvature, the outline of said mold'boards from theirpoint to their rear ends being vertically concave in cross-section,cutters upon the opposite edges of the first incline and extendingrearwardly to and upon the rear inclines, the side faces of said cutterstapering upwardly from their lower portions and their front edgessloping upwardly and rearwardly and being beveled to form a sharpcuttingedge, and a top covering the upper portions of said mold-boardsand projecting beyond the edges of the same, substantially as described.
